These separating section of,k the receptacle with the inner section members I0 may be of any suitablematerial, such. to the mattress; for example as rope, and may be attached to the Fig. 12 is an enlarged sectional view showing outer and inner walls so as to holdthem properly 55 I have illustrated in Fig. 13 a modiiled construction wherein the walls are `provided with pleats or folds II with air spaces I2, as shwn in this figure. thus forming `an insulating wall for the receptacle.

Some means is provided for holding the upper yportion of the ilexible receptacle in its up position and for permitting it to be moved down to permit a person to enter or leave the receptacle. In the particular construction illustrated the receptacle is open at the top and is provided with one or more members I3 to which the upper edge of the receptacle is connected. I prefer to loop the upper edge of the receptacle over the member I3, as shown in Fig. 5. The lower edge o! the outside section 9, atten being looped over the member I3, passes down along the member 8 and is attached at I4 to the inside member 8 by any attaching means, as by being sewed, riveted or the like. This connection may be made easily removable, as shown for example in Fig. ll, by having snap buttons I5 extending along the edge of the outer section which engages the members I6 on the inner section. By this means the edge of the outer section 9 may be easily disconnected from and connected to the inner section 8.

Some suitable means is provided, for properly supporting the upper portion of the receptacle so that it may be easily moved downwardly. In the construction herein shown there is a supporting structure which consists of a frame having the upright members I1 which are cross connected at the top by the'members I8 and I9, and the members I8 and I9 are connected together by the longitudinal members 28 and 2i. The members I1 are connected at the bottom by the members 22, 23, 24 and 25, as clearly shown in Fig. 8. The members I1 straddle the bed, as illustrated in Figs. 1, 2 and 4. Attached to the members I3 at suitable separated points are the ilexible members or cords 26, said cords being attached by the attaching devices 21, as shown in Fig. 5, and passed over pulleys 28 located in the frame members I1, which are hollow las indicated in Fig. 5. Connected with each flexible member 25 is a weight 29 which slides in the hollow members I1. These weights are preferably provided with non-metallic pieces 30 which engage the inner walls of the members I1 so as to prevent noise or vibration and insuring proper and smooth movement of the weight along the member I 1. 'I'he person desiring to enter the receptacle takes hold of the top of the receptacle, which .in this case will be the member I3, and pulls it downto the mattress, the weight 29 moving upward to permit this. 'I'he person can then enter the receptacle and upon releasing the upper edge of the receptacle the weight will pull it back to its up position as indicated in Fig. 5.

'Ihe air cooling apparatus is located above the receptacle and is mountedvand supported upon the supporting structure which straddles or encompasses the bed. In the construction shown this cooling apparatus is made in a unit which can be placed in position as a unit over the top of the receptacle. Any suitable cooling apparatus may be used. For purposes of illustration I have shown a cooling apparatus which consists of one or more cooling elements, and I have i1-l lustrated the two cooling elements 30 and 3I located at separated points and supported uponV the casing 32 in which is carried a compressor 33 and a motor 34 for operating the compressor, the motor being connected with the compressor by the belt 35. The motor andcompressor are supported upon the support 88 which is mounted on springs 81 on a base 88 which is supported by Springs 3l on the bottom ot the casing 32. This casing completely encompasses the motor and the compressor and by means of this construction noise and vibration is prevented. The cooling. elements 38 and 3l may be of any desired form and for purposes o! illustration I have. simply shown them .as coils. Located below the cooling elements 38 and 3l are the bame plates 48 which have at their lower ends the troughs 4I which catch the water produced by the moisture condensing on the coils and which moisture is discharged into the receiver 42. 'Ihe casing below the motor and compressor is provided with the air passageway 43.

When the device is in operation the air passes in through the passageways 43 and through the cooling elements 30 and 3I and past the baille plates down into the receptacle, any water due to condensation being collected in the receiver 42. 'I'he casing is also provided at the top with an opening 44. Associated with the refrigerating apparatus is a condenser element 45 and a tank 45a, see Fig. 2.

I prefer to provide an air moving device such as a fan 48 which is run from the motor shaft and which directs air against the condenser element 45. This air enters a cross passageway 41 connected with the casing 32. The passageway 41 communicates with the ducts 48 and 49 which extend longitudinally toward the front end of the device and which connect with the cross duct 58 which has the discharge 5I which preferably extends entirely thereacross, as shown in Fig. 2. It is of course understood that the cooling element, condenser element, compressor and tank 45a are connected in circuit by suitable pipes as is customary in the use of such cooling element.

The entire cooling element is preferably removably mounted upon the supporting frame work in any suitable manner. I have illustrated certain means for this purpose. There are provided, extending longitudinally along the sides oi! the refrigerating apparatus, the channels 52 into which are received the longitudinal members 2i) and 2I of the supporting frame. There are provided packing members 53 between the refrigerating apparatus and the members 20 and 2I which prevent or reduce vibration of the parts. There is also an opening 60 above the occupant. It will be seen that by means of this opening, if anything should happen so that the refrigerating apparatus does not work p/roperly, the occupant will still get plenty of air. With these openings at the top, the cold air being heaviest, settles at the bottom and will not pass out through these openings, only the warm air passing out of the receptacle. 'I'he speed of the natural draft is predetermined or regulated to t each case by arranging the fins closer or wider apart, or the depth of the coil, 'or the height of the coil above the bottom of the bed. In this way any desired control of the speed of the natural draft can be attained.

It will further be seen that the receptacle can be opened from either or both sides by simply pushing the upper frame of the receptacle down, and that the receptacle automatically assumes its normal position as the occupant enters and releases the upper frame. It will further be noted that the bed has no substantial contact or connections with the cooling apparatus. It will further be seen that I have here a portable self-contained cooling unit suitable for mounting over any bed.

'Ihe use and operation of the device are as follows:

The device may be applied to any suitable bed, chair, couch or the like and.is made the proper dimensions, depending upon the device to which it is applied. The part on which the user is to rest, such for example as the mattress, vis inserted in the flexible receptacle and the supporting element placed in position over the bed as indicated. The cooling element is then placed in position on the supporting element and the top of the receptacle connected with the flexible members. The refrigerating mechanism is then started up and the refrigerant circulated therethrough. The cooling elements then cool the air and it drops down into the receptacle. The fan drives air through the conduits 48 and 48 and 50 and out through the discharge opening 5|. The cold air which drops into the receptacle passes along the receptacle above the mattress and the party on the mattress, and the air when warmed passes up and out through the opening 59, being displaced by the cold air as it drops in, thereby producing a circulation of air through the receptacle above the occupant so that the occupant is out of the direct draft.

The discharge of the air through the discharge opening 5I may be utilized to assist in causing the warm air to pass up out of the re ceptacle, as the air discharged through the opening or nozzle at a velocity. will decrease the air pressure adjacent, causing the air in the bed to take its place and flowing with the discharged air of the nozzle.

When the occupant desires to enter the receptacle the top of the receptacle is grasped and pulled down and this causes the weights 29 to move up. When the top of the receptacle is pulled down to the proper distance from the top of the mattress, the occupant can then get in on the mattress, and upon releasing the top of the receptacle the weights will automatically move the top back up to its proper position, see Fig. 4.
